APPARATUS FOR DYEING WITH HYDROCARBONS.

SPECIFICATION forming part of Letters IPatent No. 290,110, dated December 11, 1883.

' Application filed May 28,1883. (N6 model.)

To all whom, it may concern.

'Be it; known that I, ,EUGEN RAU, of Hartford,'in the county of Hartford and State of Connecticut, have invented a new and Improved Dry-.Dyein g Machine,-of which the following is a full, clear, and exact description.

The object of any invention is to provide a new and improved machine for dyeing silks,

. mixed fabrics, or other fabricsby means-of the dry process and benzine colors.

The invention consists in a dry-dyeing machine constructed with an apparatus for saturating the previously-dried fabric in a color dissolved in benzine and oil, which apparatus is provided with a wringer for; wringing'the surplus of color out of the fabric, which is then passed into a drying-chamber, and from there between two endless blankets through ahighlyheated finishing-chamber, in which it is subjected to steam under pressure, whereby the color will be fixed and the fabric finished.

The invention also consists in various parts and. details and combinations of the same, as

5 will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate I low heated drum, A, suitably journaled in one end of the machine, and provided with hollow pivots or-other suitable devices for conducting heat or steam into the said drum. From the'drum the fabric a is passed over a series of rollers, B, journaled alternately at the top and bottoin'of alongitudinal vessel, 0, thebottom rollers being so arranged that the fabric is dipped into color dissolved in benzine and oil, which coloring-liquid is to be-contained on the bottom. of the vessel 0. A funnel, D,

is provided at one end of the vessel 0, through which funnel the coloring-liquid is filled, and is then admitted into the vessel 0 at the proper time. Below'the lower end of the spout of the funnel D an agitator or mixer, E, is provided, on one end of the shaft of which a pulleywheel, E, is mounted, which is operated by a belt, E from the driving-shaft, which continually mixes and agitates the color. the fabric has been passed through the vessel 0, it is passed between two wringing-rollers, F, journaled in standards at that end of the machine opposite the one at which the drum A is journaled, the said wringing-rollers being provided with weights, springs, or other appliances for regulating the pressure. As the fabric a, which is saturated with color, passes through between the wringing-rollers F, the surplus of the color is wrung out and flows back into the vessel 0, so that there will be no waste of color. The drumA must be After heated, so that the fabric will be thoroughly 7 dried before it is passed into the vessel 0 containing the dyeing-liquid.

Adjoining the wringing-rollers F, I have provided a high box or compartment, G, which is provided directly above the wringing-roll ers with an offset, G, in which two rollers, 9 are journaled, between which the fabric 11 passes upward into the compartment or box G, then passes over a roller, H, at the top of the box or compartment, and from there is passed downward over a roller, H, on the side of the compartment, and through a slot, I, in the side of the compartment. A coil, J, for heating, by means of steam or hot air, is arranged in the bottom of the compartment or box G, and on the top of the box or compartment a blower, K, is provided; or the top of compartw ment can be connected with a flue or with a suction-pipe of the blower, so that a draft will be created in the compartment. Under cer- ,tain circumstances the blower may be dispensed with, the hot air produced by the heated coil being suflicient to create a draft. In the box or compartment G the dyed fabric is thoroughly dried, and all moisture and vapors are carried off by the ventilator or by a draft created by a flue. From the drying apparatusthat is, the

box G-the fabric it passes into the fixing and finishing apparatus. The same consists of a high box or chamber, L, into which steam is admitted under pressure, which pressure is in dicated bythe gage L. The lower part of the compartment L is surrounded by a chest, M, to prevent the steam that escapes from the compartment L from passing into the room in which the apparatus is located. A roller, N, is journaled in the upper part of the box or compartment L, and rollers m are journaled on the edges of the side slots in the bottom of the box or compartment L, through which slots the fabric passes in and out of the said box. A hollow drum, 0, adapted to be heated by means of hot air or steam, is journaled insuitable standards on the top of the box or compartment L, and a like drum, 0, is journaled below the chest M. An endless blanket or piece of felt, S, passes over the drum 0, over rollers P, journaled at the sides of and below the said drum, which rollers I hold the blanket on the surface of the drum, over rollers Q on the chest M, over rollers R on the upper edges of the side slots in the chest M, over the rollers m on the side slots of the box or compartment L, and over the roller N in the upper part of the boxorcompartmentL. Alike endlessblanket, S, is passed over the drum 0, is held on the same by rollers 1 then passes over rollers Q, at the lower edges of the chest M, over rollers R on the lower edges of the side slots of the chest M, over the rollers m on the lower edges of the side slots of the box or compartment L, and over the roller N, journaled in the box or compartment L. Thefabriea, which has been dried in the drying-compartment G, is passed between the rollers It R and between the two endless blankets S S, and with them is carried over the roller N and out at the other side of the compartment or box L, and is wound on a drum, T. The manner in which the fabric is passed between the two blankets is clearly shown in Fig. The fabric is at all times held between the two blankets while passing through the box or compartment L, and its surface is at no time exposed to the action of the steam. The steam in the box L fixes the color and finishes the fabric. By the drying and finishing process every particle of the benzine is evaporated, and all the fumes and smells of the benzine are thoroughly removed from the fabric and the color is fixed in the said fabric.

By means of the above-described apparatus silk and other fabrics can be dyed very rapidly and can be dyed, dried, and finished in one continuous operation, and there is no waste of color.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- 1. In an apparatus for dry-dyeing, the combination of a heated drum for drying the fabric, an apparatus for immersing it in the color, a

chamber for drying the dyed fabric, and a chamber for fixing the color or finishing the fabric, substantially as herein shown and described, aud for the purpose set forth.

2.
